INK-BLOTTER.

Specification of Letters Patent.

Patented .Tune 18,1907.

Application filed November 12, 1906. Serial No. 343,110.

To a/ZZ whom t may concern:

Be it known that I7 KARL GosswEiLER, a citizen of the Empire of Germany,residing at Vienna, 48 Wolfganggasse, in the Empire of Austria-Hungary,have invented certain new and useful Improvements in Ink-Blotters, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in blotters of that type whereinthe blotting paer is provided with a relatively solid base or oundationthe paper and the base being united to form a composite blotterstructure.

The object of this invention is to provide a blotter of the generalcharacter set forth wherein means usually employed for securing theblotter sheets to the base are entirely dispensed with and wherein theconstruction is such that the v blotter sheets will when the base is inplace engage the same with sufficient force to unite and hold the partsin position.

According to my invention this feature is realized by uniting theseveral blotter sheets employed in such a manner that when the base orsupport is in place the blotter sheets will have sufficient resiliencyto effectively engage the base.

AThe invention will be more fully described in connection with theaccompanying Vdrawling and will be more particularly pointed ou't andascertained in and by the appended claims.

In the drawings-Figure 1 is a side elevation of an improved form ofblotter illustrating the main features of vmy invention and showlng abase or core inserted in place. Fig.

' 2 is an edge view of the blotter sheets showing the position that thesame assume before the core or base has been inserted.

Like characters of reference designate similar parts throughout thedierent iigures of the drawing.

The invention will be described with relation to the specific/embodimentshown but it will be understood that the invention is not to be limitedto such specific showing except for such limitations as the claimsimport.

According to my invention a plurality of sheets of blotting paper l),preferably of uniform size, are arranged in superposed relation withrespect to each other. Adjacent their ends means are provided forsecurely binding said sheets together which means as shown consists ofclips d formed of wire or other suitable material' adapted to sui-'roundsaid sheets leaving end c projecting outwardly from said clips.

In order to provide requisite stiifness and afford suflicient holdingsurfaces I provide a base which is preferably in the form' of a core aadapted to be inserted between the superposed sheets of blotting paperb. The` core o is preferably oval or lenticular in form and is insertedin place between the sheets b by opening the same through pressureexerted on the ends c, the spreading of said sheets for insertion of thecore rendering the former suiciently resilient and causing a frictionalengagement of the core by the blotting sheets suflicient to hold theparts in assembled relation. The resilient action is caused primarily bythe fact that the ends of the sheets are bound together in a fixedrelation by the clips d and when the core a is inserted the spreadingactiontends to change the fixed relation at the ends of the sheets bydrawing or pulling inwardly on the uppermost sheets and thrustingoutwardly on the innermost sheets. By providing the core in the formshown the parts orends h cause a sharp bend of the sheets near the clipsd and this tends to force the sheets to assume the collapsed posif tionshown in Fig. 2. By means of this construction it will be seen that theblotting sheets b will engage the core very securely and willeffectively hold the parts in assembled relation. It will be furthernoted that very substantial results would obtain even though the core awere not constructed as shown since the clips el would always tend tohold the ends c in Xed relation and the result of a spreading movementof'any extent or kind would tend to clamp the sheets upon the base.

In order to facilitate removal of the outer l soiled sheets all of thesheets may be perforated as at f and separately torn off in the usualmanner. y

The device of my invention is especially adapted for use in oflicessince the core can be used indefinitely with .new sets of sheets.

This arrangement is' also advantageous to the manufacturer and seller inview of the fact that the parts can be packed and shipped separately andassembled by the user. In view of the fact that a single core wouldoutlast a number of sets of blotting paper a relatively small number ofcores would be made whereas a relatively large number of sets ofblotting sheets would be IOO IOS

made and the latter could be packed and shipped in the flat or collapsedposition shown in Fig. 2.

I claim:

1. A blotter comprising in combination, a plurality of superposed sheetsof blotting paper, means uniting the ends of said paper in ixedrelation, and a lenticular core inserted between and spreading saidsheets, the resultant spring action of said sheets holding said core inplace.

2. A blotter comprising in combination, superposed sheets of blottingpaper, means uniting the ends of said sheets in fixed relation, and acore inserted between and spreading said sheets, the resultant springaction of said sheets holdin0` rsaid core in place, said core beinglocated between the points of said uniting means.

` 3. A bl'otter comprising in combination, a plurality of sheets ofblotting paper, means for connecting said sheets at the ends thereof,and means for spreading said sheets between the uniting means wherebythe resultant spring action of the sheets may serve to retain the partsin assembled relation.

In testimony wh'ereor1 I hereunto aflX my signature in presence of twowitnesses.
